Vasaline I once had some stuck to me for a skating routine and it stayed on

Gas mark 6 for 2 hours should work a treat. I can never get the bacofoil from off the skin of my sunday roast chicken.

Mike.

and you are wrapping the chicken to tight in the foil you must leave a air gap this will also allow the hot air produced to moisten the chicken and keep in the flavour, so remeber loose pouch not firmly wrapped lol
